Created attachment 557028 [details] ebuild for scipy 1.2.0_rc1 with mkl use flags scipy doesn't work with MKL BLAS from science overlay with errors at build time or run time. I got it to work with this: 1. Install numpy with mkl USE flag enabled. 2. Download scipy-1.2.0_rc1.tar.gz to /usr/portage/distfiles. 3. Put something into /usr/portage/distfiles/scipy-1.2.0_rc1-html.zip and /usr/portage/distfiles/scipy-1.2.0_rc1-ref.pdf. 4. Install the attached ebuild. 5. Set the mkl USE flag for scipy. 6. Emerge scipy. 7. Run benchmarks. Known problems with this ebuild: 1. Only works if mkl USE flag is enabled; breaks other BLAS implementations. 2. MKL library location is hard-coded in for now. 3. May break some compiled dependencies such as scikits_learn.
